Reakcja ozimych odmian lnianki siewnej (Camelina sativa (L.) Crantz) na zróżnicowany termin siewu

Abstract

In the seasons 2012/2013 - 2014/2015 an experiment was conducted in the fields of the Experimental Station Variety Examination in Przeclaw. The evaluated factors were as follows: (A) - sowing time (early, optimal, delayed) and (B) – Polish winter varieties of false flax (Maczuga, Luna, Przybrodzka). The study showed that early sowing time contributed to the lengthening of the vegetation period of plants, especially in relation to delayed sowing date. During the winter, the plant losses amounted on average to 11.3 pcs.∙m-2. The highest plant density before harvest was recorded in the plots of the optimal sowing date. The early sowing time contributed to the increase in the value of SPAD (Soil Plant Analysis Development) and the number of silicles per plant as well as seed yield. Sowing the seeds in the optimal time was increased lodging while delayed caused an increase in the MTA (Mean Tip Angle) and LAI (Leaf Area Index) index and plant height as well as the number of seeds per silicle. The thousand seeds weight was 0.85 g and was not significantly modified by experimental factors. The varieties were differed in most of the studied traits, including yield seeds. The results of the research carried out indicate that in the area of the research, the best time sowing the seeds of winter false flax is the first decade of September.
